Speeding up PADS

I'm a month in to this program and I am wondering if there are any general tips for speeding up the program. My computer is not slow, but my working style right now is often click-wait-click-wait-click-wait...

Maybe there is some basic tips for how to use it that I'm not following?

As I'm a new user, I don't know if my experience is normal or if I just have some settings wrong. Basically though I find a lot of latency for many normal commands and tasks that I feel should be instantaneous. It feels like I'm working on a PC limited by ram or something like that (or maybe a mouse clicker stuck in glue...), but this one has 16 gb and the graphics card is ok as well (nothing special, but it feels fairly speedy in other programs). I mean I can upgrade the hardware, but if everybody's experience is like this then there isn't much point.

I'm going to install the latest update (7), maybe this will improve things...
